CPU: Ryzen 5 3600
Motherboard: MSI B450M MORTAR MAX
My system was ok until 2 days ago. But now, it can't enter into Windows 10 and reboot when windows logo display. It can enter into BIOS setting. I tried change RAM, but useless. I tried detach all hard disk, only plugin a Windows 10 install usb disk, but can't enter into install UI. I tried load default BIOS setting, but useless. Only when I set the CPU cores number to 2 and shutdown Hyper-Threading，I can enter into Windows 10. If set the CPU cores number to 4 or open Hyper-Threading, I can't enter into Windows 10.
Is my Ryzen 3600 damaged?
